I was wondering if anybody has done this before? I have been converting my loft to build a layout through last year and I am now ready to start detailed layout planning prior to making the baseboards (if I go that route). I had originally planned a fiddle yard on the same level as the layout then possibly build a high level terminus above the sidings. The problem I have is that 20 odd years ago I knocked down the chimney stacks to loft level and put in an aluminium flue. The remaining chimney sits on two substantial steel gallows brackets that encroach into the area I planned for the terminus. Now I was thinking of having the terminus on the same level as the rest of the layout. Being 4 to 6 inches lower I will have a little more space under the 2 chimney supporting brackets. I would then run a track down an incline at on end of the layout to sidings under the layout then up an incline at the other end to rejoin the main layout. I can't see any reason why it shouldn't work, the incline shouldn't be too steep and it may make an interesting feature, especially if I get one on these motorised kits for the LU tube trains that you can get now.
